My name is Israel Sagi and I wanted to update you about daylight saving
time in Israel.
In 1980 there was a summer time from 3.8 to 13.9. This clock is not
updated on your maps.
Attached is a page from the Ministry of Interior for daylight saving
time in Israel
Thank you and hope you will use the information here.
For a double check, I went to the archives of Yedioth Ahronoth (the most
popular newspaper in Israel) in 1980 to make sure that there was a
daylight saving time. I would be happy to send you a photo of the
relevant articles (in Hebrew of course)
